严重烧伤患者出入量平衡的改变及其意义

Alterations of the balance between intake volume and output volume in patients with severe burns and its significance

目的 分析严重烧伤患者伤后入量、出量及出入量差值的变化规律及意义.方法 28例烧伤≥70%体表面积的成年患者,分为生存组、死亡组.记录伤后第1～7天及第10、13、16、19、22、25、28、31、34、37、40天的入量、出量及出入量差值,统计分析各时间点两组的差异.结果 在伤后各时间点,两组入量比较差异无统计学意义（P〉0.05）;在伤后大部分时间点,生存组出量显著大于死亡组（P〈0.05）,出入量之差显著小于死亡组（P〈0.05）.结论 死亡组液体正平衡大于生存组,可能与未得到有效覆盖的创面较多及毛细血管渗漏等因素有关.

Objective To analyze the alterations of the balance between intake volume and output volume in patients with severe burns and its significance. Methods Twenty - eight burned adult patients with total burn surface area （TBSA） exceeding 70% were enrolled in the study and were divided into survival group and dead group. The intake volume, output volume and the difference were recorded from the first to the forty day after burns. Results The intake volume exhibited no difference between two groups at all the time points （ P 〉 0. 05 ）. The output volumes were more in the survival group than in the dead group at most time points （P 〈 0. 05 ）. The difference was less in the survival group than in the dead group at most time points. Conclusion Positive fluid balance is more in dead group than in survival group, which may be related to ineffectively covered wounds and capillary leak.
